CO2 level readout Adafruit ccs811 CO2 sensor ... - Arduino

06-05-2021 · Hi, When I upload the example test sketch for the Adafruit ccs811 CO2 sensor the readout starts at 400 ppm and keeps gradually increasing without change in the actual CO2 level (to about 1000 in one hour). When I upload the sketch again it starts again at 400 ppm. The sensor does work. When I breathe over it I get an immediate response.

Arduino | Adafruit SCD-30 - NDIR CO2 Temperature and ...

27-06-2021 · The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing…
